I purchased three 2 litre hot water bottles from the "Coronation" range with covers; all seem to be excellent quality and I think should last a long time. The size and quality means they lose heat slowly, which is most welcome. On the whole, I'm very glad I bought them. On the downside (and the reason I can't give 5 stars to the shop): the vanilla perfume used to ease the rubber smell of new hot water bottle is ridiculously strong and seems to be much less good quality than the bottles themselves. Both my partner and I have some mild chemical sensitivities, but we can usually cope with small amounts of artificial scent, so thought would would be fine. Unfortunately this was not a small amount at all, and we've had a couple of days of itchy eyes, headaches etc., always worse just after the hot water bottle's been filled. The vanilla smell is also very strong (not unpleasant, blessedly, but... a lot). It's easing off now, thankfully (we recommend hanging the bottles and covers on the line to air out!), but it's all been a bit much. Honestly we'd have preferred to cope with the rubber smell! I'd hesitate before outright recommending the bottles, therefore, and I'd be delighted if the Hot Water Bottle Shop considered making the vanilla scent optional (or just using much less of it!). :-)
